Specification of Letters Patent.

Patented Jan. 24, 1922.

Application filed October 20, 1920. erial No. 418,179.

T 0 all whom it may concern.

Be it known that I, DANIEL F. Itonnnn, a citizen of the United States, residing at Kalamazoo, county of Kalamazoo, State of ll lichigan, have invented certain new and useful Improvements in Adjustable Diestocks, of which the following is a specification.

This invention relates to improvements in die stocks, the same being a die stock that is also adapted to hold a tap or drill.

The objects of the invention are to provide a simple and eilicient device of this character which can be very readily and strongly adjusted upon the die stock, drill or tap shank as the case may be, and be adapted to fit substantially all sizes of dies or shanks.

The objects of the invention pertaining to details and economies of structure and operation will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defines. and pointed out in the claims.

A structure which is a preferred embodiment of my invention is fully illustrated in the accompanying drawing forming a part of this specification, in which:

Fig. I is a plan view of my improved die stock structure, the handle being shown in broken section.

Fig. II is a plan view of the reverse side from that appearing in Fig. I with the outer portions of the handles broken away.

Fig. III is a detail sectional view taken on a line corresponding to l ne 33 of I and II.

Fig. IV is a detail sectional view taken on a line corresponding to line of Figs. I and III.

Fig. V is an enlarged detail longitudinal sectional View through one of the blocks showing details as to the sockets.

Fig. VI is a detail plan View in which the blocks have been reversed for the clamping of different sizes of dies.

In the drawing the sectional views are taken looking in the direction of the little arrows at the ends of the section lines and similar numerals of references refer to similar parts throughout the several views.

Considering the numbered parts of the drawing, the blocks 1 and 2 are substantially the same and opposed except that the block 2 is provided with set scr ews 6 and 7 for engaging and setting the dies disposed therein. These oppositely disposed opposed die stock blocks 1 and 2 are provided with op positely disposed shouldered screw handles 3, the same being screw threaded into the socket 4 and fitting into and shouldering against sockets 5 as seen particularly in Figs. I and V.

The blocks 1 and 2 are notched at 8 to engage the shank of a tap or drill. Slightly enlarged semi-circular recesses 9, 9 are dis posed in the opposite faces of one side of each of the blocks 1 and 2 for engaging the smaller size dies as seen in Fig. I. On the opposed edges of the opposed faces are formed circular recesses 10 for engaging a next larger size of die and cut into the opposite face is a pair of recesses 11 to en gage a larger size of die 12 as seen in Fig. -VI. A still larger size recess 13 is on the opposite side from recess 11. These dies are all provided with depressions and are locked for additional security by the set screw 6 or 7. The dies themselves may or may not be adjustable, my improved die stock being adapted to any kind.

I desire to state that while I have shown my improved die stock adapted to many sizes of dies it is also adapted to a structure handling a single size of die. I desire to claim the features broadly and also to claim the special arrangement and features whereby a series of dies may be effectively held.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

l. A die stock comprising a pair of reversible similar clamp members with a series of clamping seats on opposite sides thereof containing at one side screw threaded sockets and at the other side plain sockets disposed. in opposed relation, handles with screw threaded portions at their inner ends to engage the screw threaded portions of said blocks and shouldered to coact with the plain portion of the oppositely disposed similar block, and set screws in one of said blocks for locating the dies, coacting as specified.

2. A die stock comprising a pair of reversible similar clamp members with a series of clamping seats on opposite sides thereof containing at one side screw threaded sockets and at the other side plain sockets disposed in opposed relation and handles with screw threaded portions at their inner ends to engage the screw threaded portions of said blocks and shouldered to coaot with the plain portion of the oppositely disposed 7 blocks for locating the dies, coacting as spec- 4. A die stock comprising a pair of similar clamp members containing at one side screw threaded sockets and at the other side plain sockets disposed in opposed relation, handles with screw threaded portions at their inner ends to engage the screw threaded portions of said bloeks and shouldered to coaot with the plain portion of the oppositely disposed similar block, and set screws in one of said blocks for locating the dies, coacting as specified. 7

In witness whereof I have hereunto set my hand and seal in the presence of two witnesses.

DANIEL F. ROEDER.
